Answer:

  3a by 4a

Step-by-step explanation:

For dimensions L and W, the area and perimeter are ...

  A = LW = 12a^2

  P = 2(L+W) = 14a

Using the second equation, we can find L:

  L +W = 7a . . . . . divide by 2

  L = 7a -W

Substituting into the area formula gives the quadratic ...

  (7a -W)(W) = 12a^2

  W^2 -7aW +12a^2 = 0 . . . . arrange in standard form

  (W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)

Then we have the two solutions ...

  W = 3a, L = 4a

  W = 4a, L = 3a

The rectangle dimensions are 3a by 4a.

Answer:

A) x = 12

Step-by-step explanation:

Answer:

Step-by-step explaintation

a2 + 10a = 24

10a + a2 = 24

10a + a2 = 24

Solving for variable 'a'.

Reorder the terms:

-24 + 10a + a2 = 24 + -24

Combine like terms: 24 + -24 = 0

-24 + 10a + a2 = 0

Factor a trinomial.

(-12 + -1a)(2 + -1a) = 0

Set the factor '(-12 + -1a)' equal to zero and attempt to solve:

Simplifying

-12 + -1a = 0

Solving

-12 + -1a = 0

Move all terms containing a to the left, all other terms to the right.

Add '12' to each side of the equation.

-12 + 12 + -1a = 0 + 12

Combine like terms: -12 + 12 = 0

0 + -1a = 0 + 12

-1a = 0 + 12

Combine like terms: 0 + 12 = 12

-1a = 12

Divide each side by '-1'.

a = -12

Simplifying

a = -12

Answer:

x = -87

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, subtract 265 from both sides of the equation:

3x + 265 (-265) = 4 (-265)

3x = 4 - 265

3x = -261

Next, divide 3 from both sides:

(3x)/3 = (-261)/3

x = -261/3

x = -87

x = -87 is your answer.

~

Answer:

If you're looking for the value of x, it's -87.

Step-by-step explanation:

1. Subtract 265 from both sides

3x+265-265 = 4-265 = 3x = -261

2. Divide by 3 to get the variable by itself

3x/3 = -261/3. = -87

x = -87

Answer:

y = 7

Step-by-step explanation:

Mathematically, according to the Pythagoras’ theorem;

The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides

The hypotenuse is the side that faces the right angle and it is represented by the square root of 85 here

Thus, we have it that;

(√85 )^2= 6^2 + y^2

85 = 36 + y^2

y^2 = 85-36

y^2 = 49

y = √49

y = 7

Answer:

x < 6

Step-by-step explanation:

18 > 12 + x

Switch sides:

12 + x < 18

Subtract 12 from both sides:

12 + x - 12 < 18 - 12

x < 6

The solution of the inequality is,

⇒ x < 6

And, Graph is shown in image.

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ 18 > 12 + x

Now, We can solve the inequality as;

⇒ 18 > 12 + x

Switch sides:

⇒ 12 + x < 18

Subtract 12 from both sides:

⇒ 12 + x - 12 < 18 - 12

⇒ x < 6

Thus, The solution of the inequality is,

⇒ x < 6

Answer:

y > -2/3 x + 3

Step-by-step explanation:

First we find the equation of the dashed line.

y = mx + b

We see b = 3.

The slope is -2/3.

The equation of the line is

y = -2/3 x + 3

The line is dashed, not solid, and the shading is above the line, so the inequality is

y > -2/3 x + 3

Answer:

1232 penny

Step-by-step explanation:

Given the value of a bank account, B, after x years is represented by the equation B = 1000(1+.014)^x.

To determine the account worth after 15 years, we will substitute x = 15 into the expression as shown;

B = 1000(1+.014)^x.

B = 1000(1+.014)^15

B = 1000(1.014)^15

B = 1000(1.2319)

B = 1231.9penny

Hence the value after 15years is 1232 penny (to the nearest penny)

Answer:

Required amount of aluminium foil = 522.80 [tex]in^{2}[/tex]

Step-by-step explanation:

The shape of the large Hershey kisses can be compared to that of a cone. So that;

the surface area of the kisses = [tex]\pi[/tex][tex]r^{2}[/tex] + [tex]\pi[/tex]rl

Let the slant height be represented by l. Applying the Pythagoras theorem;

[tex]l^{2}[/tex] = [tex]10^{2}[/tex] + [tex]8^{2}[/tex]

   = 100 + 64

   = 164

l = [tex]\sqrt{164}[/tex]

l = 12.81 in

Thus,

surface area of the kisses = (3.14 x [tex]8^{2}[/tex]) + (3.14 x 8 x 12.81)

                     = 200.96 + 321.7872

                     = 522.7472

surface area of the kisses = 522.75 [tex]in^{2}[/tex]

Thus, the amount of aluminium foil required to wrap the kisses is 522.80 [tex]in^{2}[/tex].
